MODEL UMC UNIVERSAL MANIFOLD CHECK ASSEMBLY

MODEL UMC UNIVERSAL MANIFOLD CHECK ASSEMBLY

GENERAL DESCRIPTIONThe Globe Series “UMC” Universal Manifold Check is a first of its kind, UL Listed and FM Approved, complete floor control station or shotgun riser assembly. It is pressure rated for 300 psi (20,6 bar). It provides the most compact “footprint” while delivering all of the necessary components for your floor control station as required by the NFPA Stan-dards. With its multiple available configurations, it allows the contractor to order the suitable configuration for the site specific needs. The “UMC” Universal Manifold Check is more than just a traditional stand-alone manifold. It serves as a complete floor control station as well as a complete shotgun riser assembly inclusive of Control Valve with In-ternal Supervisory Switch; Check Valve; Flow Switch; Test and Drain Assembly; Adjustable Pressure Relief Valve As-sembly pre-piped to drain; supply gauge (4", 6" and 8") and system gauge (1 1/4" through 8"). The “UMC” Universal Manifold Check replaces the need to order individual “Riser Manifolds” plus control valves, check valves, and relief valve kits as all of these components are integrated into the one compact design, saving space as well as the labor to connect these separate components. For sizes 3" and smaller, an 18" long stainless steel braided flexible hose is included with the UMC for connecting the Test and Drain valve to a drain stack. The design takes into account both “left-hand” and “right-hand” orientations. (8" version avail-able preassembled in right-hand orientation only)

FLOOR CONTROL ASSEMBLYThe UMC may be utilized to meet the NFPA 13 require-ments for Floor Control Valve Assemblies where there are multistory buildings exceeding two stories in height requir-ing zoning by floor or whenever separate control and floor zoning is specified. The UMC has been engineered with space savings in mind for those commonly installed appli-cations in stairwell landings and small alcoves. All UMC assemblies include the NFPA 13 required Listed Pressure Relief Valve which is pre-piped to drain. The relief valve is preset for 175 psi and is adjustable to 310 psi for high pres-sure system conditions. In addition to the relief valve, the UMC is equipped with a Test and Drain Valve. The Test and Drain Valve contains a test orifice of K2.8 so that it may be utilized for flow testing any system with sprinklers having K-Factors of 2.8 or larger.

Note: NFPA 13 requires that a test connection providing a flow rate equal to or less than one sprinkler of a type having the smallest orifice on the system is to be provided.

A pressure gauge is provided above the check valve clap-per for sizes 1¼” through 3” to meet the gauge require-ment per NFPA 13 for Floor Control Assemblies. Typically the supply side gauge is not required for multistory build-ings with floor control stations as a system gauge would be on the main feed/riser but all Model UMC Manifold Check Valves are equipped with a 1/4" (DN 8) port below the clap-per to accommodate a second gauge if desired.

SHOTGUN RISER ASSEMBLY"Shotgun Riser Assemblies" are those assemblies which are typically installed in vertical orientations on individual system Risers. The Globe “Shotgun” Riser Manifold As-sembly is available in 4 inch (DN 100), 6 inch (DN 150), and 8 inch (DN 200) sizes and is equipped with a control valve; check valve; flow switch; test and drain valve with NFPA required pressure relief valve; 2 gauges (system and supply). Sizes 4 inch (DN 100), 6 inch (DN 150), and 8 inch (DN 200) are equipped with a pressure gauge on both sys-tem side and supply side of the check valve clapper. The 8" UMC consists of a Universal Manifold, a Victaulic Series 717 Grooved Check Valve and an optional Victaulic Series 705 Grooved Butterfly Valve.

MODEL UMC MANIFOLD CHECK VALVE ASSEMBLY LEFT HANDED VS RIGHT HANDED

Both the shotgun riser assembly and the floor control station assembly are available as left handed or right handed assembly. The determining factor of the left handed vs right handed is the position of the Model UTD Test and Drain. While looking at the faceplate with the Model UMC valve in the vertical orientation and flow upward (shotgun riser orientation), the posi-

tion of the Model UTD Test and Drain determines the "Hand" of the valve. If the Model UTD Test and Drain is connected to the port on the right side of the valve body, it is considered a right handed assembly. If the Model UTD Test and Drain is connected to the port on the left side of the Model UMC valve the assembly is considered left handed.

FIGURE 8: MODEL VSR-M FLOW SWITCH TYPICAL WIRING DIAGRAM

FLOW SWITCH REQUIREMENTSThe Model UMC Floor Control/ Shotgun Riser assembly is sold inclusive of a Potter VSR flow switch. The flow switch utilizes exactly the same electrical and switch components as the Potter VSR flow switch but includes an adapter which attaches directly to the Model UMC Manifold Check as-sembly. This adapter has been tested as part of the UMC assembly to ensure the hydrostatic strength as well as the placement and sensitivity of the paddle is within the criteria set forth by UL and FM. The part number for the flow switch assembly can be found

in the replacement parts section of the technical literature. The Potter VSR Flow switch includes 2 sets of switches, one set can be used to activate the central fire alarm system while the other set can be utilized to activate a local alarm (if necessary). See figure 8 for a typical wiring diagram for the Model VSR Flow switch.

Note: For more information on the flow switch see www.pottersignal.com.

INSTALLATIONThe Model UMC Floor Control/ Shotgun Riser assembly is sold as a complete unit, assembled and shipped in a single box. The Model UMC Manifold Check Valve must be installed in an accessible and visible location, which is maintained at or above a minimum temperature of 40ºF (4ºC). The UMC may be installed in the horizontal or vertical (flow upward) orientation. All valves must be installed in accordance with the ap-propriate installation standard (i.e. NFPA 13 or other). All electrical connections must be made per the applicable in-stallation standard and/or the National Electric Code (i.e. NFPA 70, NFPA 72 or other). Proper hydrostatic test procedure must be followed per NFPA 13. It is not necessary to remove the ARV Relief Valve prior to system hydrostatic test. The Adjustable ARV may simply be temporarily adjusted to a pressure above the test pres-sure during the hydrostatic test. Be sure to return the ARV Relief Valve to it's normal setting after the completion of the hydrostatic test.

MODEL ARV RELIEF VALVE SETTING PROCEDUREThe Globe 1/2 inch Model ARV, 300 psi Adjustable Pres-sure Relief Valve, is factory set to relieve at a pressure of approximately 175 psi (12 bar).The Pressure Relief Valve may be reset to a higher pres-sure; however, it must be reset to relieve at a pressure which is in accordance with the requirements of the au-thority having jurisdiction, typically nominal 10 psi (.7 bar) above the expected normal system pressure.To reset the Model ARV pressure relief valve, use an ad-justable crescent wrench, to turn the hex cap clockwise for a higher pressure setting or counter-clockwise for a lower pressure setting. Use the calibrated lines on the stem for an approximate relief pressure setting. 1 full turn of the hex cap will result in approximately 25 psi increase or de-crease. To verify the new setting, isolate the Model ARV relief valve and use a small hydrostatic pump attached to the supply. Increase the pressure at the relief valve to 10 psi above the expected normal system pressure. Readjust the ARV as needed to maintain a 10 psi higher relief setting.

TESTINGReference NFPA 25, Standard for the Inspection, Testing and Maintenance of Water-Based Fire Protection Systems. Before proceeding with any tests involving water flow, the following precautions need to be taken:

STEP 1. Check the location where the test connection discharges to make sure that all is clear and that there is no possibility of the water flow causing damage or injury.

STEP 2. Check the end of the test connection to make sure that it is unobstructed. To achieve a satis-factory test, there must be an unrestricted flow of water when the test valve is wide open.

STEP 3. Check for alarm connections to a central sta-tion or fire department. If such connections are found, give proper notice to the signal receiv-ing station before proceeding with the test.

Note: A main drain test may also operate local fire alarms unless they are tem-porarily disabled.

MAINTENANCEThe owner is responsible for the Inspection, Testing and Maintenance of their fire protection system.System inspection, testing and maintenance shall be per-formed in accordance with this section as well as NFPA 25 or other applicable Standard to insure the integrity of the entire system, including alarm functions as well as other system components. Any impairments must be immedi-ately corrected.Before closing a system main control valve for mainte-nance work on the fire protection system, obtain permis-sion to shut down the affected fire protection system from the proper authorities and notify all personnel who may be affected.

Note:

All valves should be carefully inspected, tested, and maintained in accordance with NFPA 25 or other applicable Standard.

It is important to ensure a clean water supply free of debris and solid particles such as sand, gravel, or mud. If, during an inspection of a water control valve, sediment or free particles of matter are noted, a further examination of internal valve parts is necessary. All deposits should be removed from all operating parts and ports. Where difficulty in performance is experienced, the manu-facturer or its authorized representative shall be contacted before any field adjustment is to be made. UMC Clapper Facing. The rubber clapper facing should be checked for wear or damage and to determine that it is free of dirt and other foreign substances. If found to be worn or damaged (e.g., foreign matter embedded in the surface; cut or torn facing), the facing should be replaced. If it is dirty, it should be cleaned. Compounds which could dam-age the rubber fac ing must never be used. Should clapper facing replacement become necessary, the following steps should be performed;

Note: Before performing the following steps, insure that the system has been depressurized and drained.

Clapper RemovalSTEP 1. Remove handhole cover. STEP 2. Remove hinge pin plugs from front and back

of UMC.STEP 3. Using allen wrench, push hinge pin from back

of UMC towards front.

STEP 4. Once hinge pin is accessible, carefully grab with pliers or similar to pull hinge pin out of body.

Note: Care must be taken to confine clapper spring while extracting hinge pin from body. Spring is under tension around hinge pin. It is also recommended to cover drain port to minimize the possibility of spring inadvertently dropping into drain piping.

STEP 5. Carefully remove clapper assembly from UMC.Clapper Replacement. When replacing clapper, be sure clapper spring has been properly positioned around hinge pin such that tension is applied to the clapper by the spring.

Seat Ring. The seat ring should be checked for nicks and for stones, dirt or other foreign matter. It should be cleaned thoroughly. If the seat ring is found to be damaged, UMC should be replaced.

Water Flow Switch (VSR-M). There is no maintenance re-quired, only periodic testing and inspection. Should switch be found to be malfunctioning, refer to Potter Signal Techni-cal Literature for guidance.

Model ARV Adjustable Relief Valve. Valve is not field ser-viceable. If inadvertent leakage is ob served, first test the pressure setting utilizing the procedure outlined in the ARV Relief Valve Setting Procedure. If valve does not respond to field adjustments, valve shall be replaced.

Note:

Visual calibration lines on valve are used for approximate adjustment. Verify pressure setting with pressure gauge.
